As discussed in the mail thread <https://groups.google.com/a/isocpp.org/forum/ #!topic/std-discussion/T64_dW3WKUk> "Calling noexcept function throug non- noexcept pointer is undefined behavior?", such a call should not be UB. However, Clang currently warns about it. This change removes exception specifications from the function types recorded for -fsanitize=function, both in the functions themselves and at the call sites. That means that calling a non-noexcept function through a noexcept pointer will also not be flagged as UB. In the review of this change, that was deemed acceptable, at least for now. (See the "TODO" in compiler-rt test/ubsan/TestCases/TypeCheck/Function/function.cpp.) This is the compiler-rt part of a patch covering both cfe and compiler-rt.
